NITED STATES CHARLES HAMMER, OF HOLLIS COURT BOUIEVARD, NEW -YORK.

BAND-SEALING FRICTION CATCHUI. CAP.

Application filed July 7,

To all whom it may concern:

Be it known that'I, CHARLES HAMMER, a citizen of the United States, residing at .llollis Court Boulevard, in the county of (Queens and State of New York, have invented certain new and useful Improvements in Band-Sealing Friction Catchup Caps, of which the following is a specification.

This invention relates to band sealing catchup caps, the object thereof being to provide an improved friction catchup cap adapted to be effectively sealed on a container, such as a glass container, by means of a sealingband.

Catchup caps have been made with threads intended to be sealed on a container by means of a sealing band, but it is not pos sible in these forms of caps to force the cap down by pressure, and then seal it by means of a friction band, since as the caps are prov rided with threads for rotating the cap on to the neck of the catchup bottle, mechanical pressure cannot be used to force the cap on to the bottle and'hold it there during the application of the sealing band, In other Words the cap must' be rotated on to the bottle and then the sealing band applied. Consequently, the bottle cannot be as effectively sealed in the first instance by thls rotation, as it canbe by mechanlcal pressure directly applied to the top of the cap, and therefore the object of the present lmprovement is to provide an improved cap of this description, which can be automatlcally sealed by mechanical pressure without the necessity of rotating the cap on to the container, and then held sealed by a sealing band, so that when the band s removed the cap can be reused and for tli 1s purpose the cap is in the form of a fIlCtlOIl cap, which can be readily slipped .on and off without the necessity of rotating it on the threads of the bottle. a I

This construction enables the user to see when he purchases the article that 1f th'e sealing band is intact the contents have not been tampered with. One of the disadvantages of a threaded catchup cap is that in the repeated pouring of small portlons of the contents. of the bottle, the catchup accumulates around the threads of the bottle and the cap where, it hardens and is effected by the atmospherebecoming dark or black, more or less unsanitary, and also presenting fo ming a part of this specification 1923. Serial NO. 650, 116.

ened matter also somewhat interferes with an efiicient rescaling of the bottle. In the present improvement there are no threaded surfaces for the accumulation of the contentsv of the bottle since the cap has a comparatively smooth interior surface which can be readily cleansed and can be readily sllpped or snapped on and off, and by means of its friction engagement efficiently held on to the bottle after the removal of the sealing band. In the drawings accompanying and i 1 is a part sectional view of this impro ved cap and its sealing band applied to a catchup' bottle; Fig. 2 is a perspective view of the capr'emoved from the bottle and its sealing band; Fig. 3 is a sectional view of the sealing band detached; Fig. 4 is a perspective view of the sealing band; and Fig.

5 1s a perspective view of a polygonally formed friction cap adapted for use on a catchup bottle wit-h a sealin band.

Similar characters of reference indicate corresponding parts in the several views. Beforeexplaining in detail the present improvement and mode of operation thereof, it is desired to have it understood that the invention is not limited to the details of construction and arrangement of parts which are illustrated in the accompanying.

drawings, since the invention is capable of other embodiments, and the phraseology which is employed is for the purpose of descri tion and not of limitation,

T is improved catchup cap comprises a top 2 and a long depending cylindrical skirt or flange 3. The cylindrical skirt or flange is usually seamed in some suitable way 8' and in two-piece catchup caps is interlocked with the top by a suitable interlocking seam. The long depending flange terminates at-its lower edge in a strengthened edge 4 which is preferably obtained by rolling, curling or beading said lower edge thereby securing protection from rust and unsanitary conditions, as 'well as preventing the cutting'of the hands of the .user. The flange is provided with a deformed portion forming an" surface for the handling of the cap.

annular band or inwardly extending portion of less diameter than the normal diameter of the cap at each side of said band whereby this band is no greater and is usually slightly less than the diameter of the side sealing face of the container. This band is adapted to frictionally contact with the outer or side sealing surface of the catchup bottle or container throughout an appreciable width of the band whereby it will be held thereon and can be readily snapped on and ott' the bottle 6, which is provided with a shoulder 7 located rela' tively remote to the top or upper edge of the bottle. Owing to the deep flange or skirt necessary in catchup caps it is ditlicult to draw such a cap from one piece of metal and therefore the skirt and top as hereinbeforc stated are usually formed separately and interlocked by a suitable seam as 8. Located in the top of the cap is a sealing disc 9 by means of which the bottle is sealed when the cap is in place. In the form of cap shown in Figs. 1 and 2 it is provided with corrugations 10 assisting to reinforce the cap flange and also forming a roughened These corrugations are located above the friction sealing surface.

In the form of cap shown in Fig. 5 it is provided with a deformed or polygonally formed flange 11 which serves all of the purposes of corrugations and the annular frie tion band 5, that is to say, these polygonal surfaces 11 extend all around the cap and form practically an inpressed continuous band having a frictional engagement with the outer wall of the bottle and also form a gripping means as well as a strengthening means for the flange of the cap.

For locking either form of cap on to the bottle a suitable sealing band 12 is provided, the upper edge of which is bent or turned over the rolled or beaded lower edge of the cap as at 13 while the lower edge 14 of the sealing band is forced or bent inwardly under the shoulder of the bottle, thus efl'ectively sealing the cap on to the bottle. This sealing band is readily separable by the user since its ends may overlap and if preferred be interlocked in some suitable way.

Thus by suitable mechanical pressure applied to the top of the cap, it is forced downwardly on to the bottle to properly seal the contents and then the sealing band is applied, thus locking the cap in place against tampering or premature removal, so that the user upon urchase of the bottle can tell at a glance wiether the cap has been removed or not. 'Upon the removal of the sealing band the cap can be snapped off without rotation and easily replaced and effectively held thereon -by the annular friction surfaces or the polygonal surfaces of the cap so that the cap can be readily reused. It

will be observed that there are no threads or similar surfaces adjacent to the open end of the cap for the lodgen'ient of the bottle contents, and consequently this improved cap is more sanitary and more easily applied and removed, while giving as'etl'ective a seal as a threaded cap. From the foregoing it will be observed that I have provided an improved catchup cap having a pair of sealing hands, one comprising a preformed annular friction sealing band in the skirt of the cap and the other a detachable sealing band applied to the skirtand to the shoulder of the container so that the two bands initially secure and seal the container, but when the detachable band is removed, the cap can be readily snapped on for reuse and will he by means of the preformed annular friction hand not only secured, but sealed on the catchup bottle as not only to preserve the contents of the bottle but prevent the spilling thereof should the bottle be tipped over. Thus I have provided not only a sanitary catchup cap but a double side scaled catchu p cap in the first instance, and upon the removal of the detachable band the cap will subsequently in the reuse thereof ell'ectively seal the contents, and I believe I am the tirst to provide. a snap on double side seal catchup cap.

From the foregoing it will be observed that this improved cap seals the contents at three points to wit. at the top end or mouth of the bottle, at the side by means of the annular friction band and again at the shoulder.

It is to be understood that by describing in detail herein any particular form, structure, or arrangement it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, I claim:
